Prepping with Chlorhexidene

The application of the Surgi-Sign® tattoo and its subsequent removal did not impair the effectiveness of chlorhexidene in reducing bacterial growth from sampled human skin.

Clinical Study #1 

This study demonstrates that using a novel new marking system based on a rapidly dissolving temporary tattoo greatly improves performance of key elements of the Universal Protocol including performance of the Time Out procedure.

The application of the Surgi-Sign® Marking System does not contaminate the skin surface or impede the disinfection of the surgical site using 7.5% Povidone-Iodine USP Scrub Solution or 10% Povidone-Iodine solution.
